  A surplus on the current account of the balance of payments occurs when the value of a country's exports of goods and services, plus net primary and secondary income, exceeds the value of its imports. This means net exports (X-M) are a positive figure. While often viewed as a sign of economic strength, it is debatable whether a surplus is always beneficial for an economy.

  On one hand, a current account surplus can bring significant benefits. As net exports are a component of aggregate demand (AD), a surplus provides a net injection into the circular flow of income. This causes the AD curve to shift to the right, leading to an increase in real GDP and economic growth. The resulting higher demand for labour can reduce cyclical unemployment. For example, Germany's consistent current account surpluses for much of the 21st century have been linked to its strong manufacturing sector and low unemployment rates. Furthermore, a surplus allows a country to become a net creditor to the rest of the world, building up its reserves of foreign currency or acquiring foreign assets. This strengthens its international investment position and can provide a future stream of primary income, enhancing long-term economic stability.

  However, the benefits of a current account surplus are not guaranteed and can be accompanied by significant drawbacks. The rightward shift in AD, if the economy is operating near its full employment level of output, will not lead to much growth but will instead create demand-pull inflationary pressure. This erodes the real value of incomes and can make the country's exports less competitive over time, negating the initial advantage. Moreover, a persistent surplus increases the demand for the country's currency on the foreign exchange market. This leads to an appreciation of the exchange rate, which makes exports more expensive for foreign buyers and imports cheaper for domestic consumers. This can harm the profitability of export-oriented industries and domestic firms competing with imports, potentially leading to structural unemployment and deindustrialisation.

  The underlying cause of the surplus is also a critical factor. A surplus driven by strong, competitive exports is a sign of a healthy economy. In contrast, a surplus may be caused by depressed domestic demand, where low consumer and business confidence leads to a collapse in spending on imports. In this scenario, as was arguably the case for Japan during periods of its economic stagnation, the surplus is a symptom of a weak domestic economy, not a source of benefit. Finally, large and persistent surpluses in one country necessitate deficits in others, which can lead to international tensions and accusations of unfair trade practices or currency manipulation. This can provoke retaliatory protectionist measures, such as tariffs, from trading partners, ultimately harming global trade and the surplus country itself.

  In conclusion, an economy does not always benefit from a current account surplus. While a modest surplus driven by international competitiveness can stimulate growth and employment, a large and persistent surplus carries substantial risks. These include demand-pull inflation, a damaging currency appreciation, and the potential for international trade disputes. The desirability of a surplus depends heavily on its cause, its size, and the prevailing conditions within the domestic economy. Therefore, a position of near-balance on the current account is often considered a more sustainable and beneficial long-term macroeconomic objective than a large, sustained surplus.

  How it reaches the top band

  • Knowledge / Analysis / Evaluation — The essay demonstrates detailed knowledge by accurately defining the current account surplus and its role as a component of AD. The analysis is developed and two-sided, first explaining the benefits (AD shift leading to growth and lower unemployment) and then providing a counter-argument with equal depth. It analyses the drawbacks of inflation (linking the AD shift to the position on the AS curve), exchange rate appreciation (explaining the mechanism via demand for the currency), and the negative implications of a surplus caused by weak domestic demand. The evaluation is sophisticated and woven throughout, but is crystallised in the conclusion. It directly addresses the 'always' in the question and provides a reasoned judgement that a surplus is not always beneficial, supporting this by referencing key dependencies: the cause of the surplus, its size, and the state of the economy. The use of Germany and Japan as contrasting real-world examples adds depth and supports the argument effectively.

  Common ways to drop marks

  • Providing a one-sided answer that only lists the benefits of a surplus, failing to 'assess' the potential drawbacks.
  • Confusing the current account with the financial/capital account, for example by stating that FDI inflows cause a current account surplus.
  • Making assertions without explanation, such as stating 'a surplus causes inflation' without explaining the demand-pull mechanism via an AD shift when the economy is near full capacity.
  • Failing to provide a clear final judgement that directly answers the question of whether a surplus is 'always' beneficial.

  Examiner tip: For 'assess' questions, always build your argument by explaining the benefits, then critically evaluating the drawbacks or limitations, before reaching a final, supported judgement.
